Haven’t been able to figure this out yet. Wife is driving her new car but so far, has only parked it in store or mall parking lots that don’t have dedicated or timed/restrictive parking. However, today I noticed two yellow chalk marks on the right front tire and one on the left front that weren’t there several days ago (I checked tire pressures a couple days ago and would have noticed them). My conundrum is, why would someone be marking her tires if she’s only parking in lots like Kroger’s, Walgreens, Fresh Market or shopping centers for a few hours and only using general use unrestricted parking spots? I’m not coming up with any ideas on this one!
